Chapter 11, Problem 11.95QP

Interpretation Introduction

Interpretation: An increase in the boiling point of given mass of chloroform on dissolution of given mass of eugenol is given. The molar mass and the molecular formula of the given compound are to be calculated from the given mass percentage of the elements.

Concept introduction: The number of moles is calculated by the formula,

$\text{Number}\text{of}\text{moles}=\frac{\text{Mass}}{\text{Molar}\text{mass}}$

The number of units $\left(n\right)$ of empirical formula is calculated as,

$n=\frac{\text{Molar}\text{mass}}{\text{Emperical}\text{formula}}$

To determine: The molar mass and molecular formula of the given compound.
